Installation and sampling of vadose zone monitoring devices
A vadose zone monitoring system was installed in a sanitary landfill near the Y-12 facility on the Department of Energy's Oak Ridge, Tennessee Reservation. The work was completed as part of the LLWDDD program to develop, design, and demonstrate new low level radioactive waste disposal monitoring methods. The objective of the project was to evaluate the performance of three types of vadose zone samplers within a similar hydrogeologic environment for use as early detection monitoring devices. The three different types of samplers included the Soil Moisture Equipment Corporation Pressure-Vacuum samplers (Models 1920 and 1940), and the BAT Piezometer (Model MK II) manufactured by BAT Envitech, Inc. All three samplers are designed to remove soil moisture from the vadose (unsaturated) zone. Five clusters of three holes each were drilled to maximum depths of 45 ft around part of the periphery of the landfill. Three samplers, one of each type, were installed at each cluster location. Water samples were obtained from 13 of the 15 samplers and submitted to Martin Marietta for analysis. All three samplers performed satisfactorily when considering ease of installation, required in-hole development, and ability to collect water samples from the vadose zone. Advantages and disadvantages of each sampler type are discussed in the main report.
